MOLD FOR COMPOUND INGOTS.

SPECIFICATION forming" part of Letters Patent No. 240,727, dated April26, 1881.

application filed December 17, 1880. (No model.)

To all whom it may concern:

Be it 'known that I, ALFRED E. JONES, of Newark, in the county of Essexand State of New Jersey, have invented an Improvement in Molds forCompound Metal lngots,of which the following is a specification.

Moldshave been made in two or more parts for the reception of castmetal. In some instances one portion of the mold has been removed andanother substituted, so as to leave the necessary space into which steelor other metal can be cast directly upon the iron. It is difficult tothus exchange parts of the molds while hot. In other instances awedge-shaped filling-plate has been placed in the mold at one side, andthe same has been withdrawn after the iron has been cast; but the spaceleft for the steel is not parallel, and hence one part is thicker thanthe other, and owing to the unequal expansion of the metal-mold the saidwedge is difficult to withdraw, and sometimes it becomes immovable.

Myinvention is made for avoiding the aforesaid difficulties; and itconsists in combining with the mold a peculiar hinged cover, that can beeasily opened on closed, and a removable plate at the inside ofthccover, so that after the iron has been cast into the mold the coveror side may be swung open sufficiently to remove the pressure upon theinclosed plate, and then the plate removed and the cover or sidereplaced, and the steel cast into the parallel space that is thus leftin the mold.

111 the drawings, Figure l is a vertical section of the mold completeand ready for use. Fig. 2 represents the same as open for the removal ofthe plate. Fig.3 is a section at the line a: a", and Fig. 4 is an edgeview of the removable plate.

The mold is made with the three sides a, b, and c and bottom deitherinone piece or firmly connected together. The foot or base of the moldextends, as at e, to form a hinge or hearing for the movable side orcover f to swing upon.

This cover is made with a recess for the recep- 5 tion of the movableplate g, and the edges of the coverf set closely against the edges ofthe mold. The lower part of the cover has a projection, 'i, that setsinto the bearing 6, forming with it an open hinge for the cover to swingupon.

it is to be understood that the mold is closed and held by the movablering I, and the plate g is in the cover. The iron is cast into the mold,

and assoon as it is sutficiently consolidated the ring l is lifted, thecover f swung "back, and the plate 9 removed, and then the mold isclosed again and the steel poured into the space previously occupied bythe plate 9, so that the two metals weld together. 9 should be providedwith a hoolti k, at the upper end, to sustain the plate in its properposition relatively tothe cover.

The removable plate is to be parallel; but

the same may be of anydesired shape sectionally to form a bar or platecorresponding to the steel or other metal cast into the mold.

I claim as my invention 1. The combination, with the mold a I) c d, of

a swinging cover,f, and the removable plateg,

of the mold, which plate is liberated'byopen- 8oing the mold, and isremoved after one metal has been cast, substantially as set forth.

Signed by me this 11th dayof December, A. D. 1880.
